FR2-5 2rs Bearing Product Overview & Core Advantages
The FR2-5 2RS is a miniature sealed ball bearing designed for compact applications requiring reliable performance. As a single row deep groove ball bearing with integral rubber seals (2RS), it provides effective protection against contamination while retaining lubrication. This bearing is engineered to handle radial loads primarily, making it ideal for applications where space is limited but dependable operation is critical. Its inch dimensions and ABEC1 precision class ensure consistent performance in various industrial and commercial equipment.
FR2-5 2rs Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| FR2-5 | Bearing series designation with 1/8" bore diameter and specific cross-section |
| 2RS | Double rubber contact seals on both sides for superior contamination protection |
FR2-5 2rs Bearing Structural Features & Performance Benefits
Robust Construction: Manufactured from chrome steel rings and balls with stainless steel cage, providing excellent durability and corrosion resistance. The deep groove raceway design enables efficient radial load capacity while accommodating minor axial loads.
Enhanced Sealing Performance: The double rubber seals (2RS) create an effective barrier against dust, moisture, and other contaminants, significantly extending bearing service life in challenging environments.
Precision Engineering: With ABEC1 tolerance class and controlled radial internal clearance (MC3: 0.00008" to 0.0005"), this bearing delivers smooth operation and consistent performance across its operating temperature range of -86 to 230 °F.
Optimized Design: Features six precision-ground chrome steel balls (0.06252" diameter) for balanced load distribution and smooth rotation, contributing to the bearing's limiting speed of 60,000 rpm.
